Abstract

Global warming and energy consumption have spurred the research and development of proton exchange membrane fuel cells (PEMFCs), a high-energy-density and zero-emission energy conversion device. Currently, the predominant commercial catalyst employed for hydrogen oxidation reaction (HOR) in PEMFCs anode is Pt/C, and the efficiency of Pt-based catalysts is significantly undermined by the presence of CO mixed in the PEMFCs anode reactants. The incorporation of transition metals can modify the electronic structure of Pt-base catalysts and reduce the adsorption energy of CO on the platinum surface, thereby enhancing the CO tolerance. This timely review aims to present the crucial role of Pt-based alloy strategies for anti-CO poisoning of PEMFC anodes and performance optimization for HOR, and to offer a current overview of the research field. By following the demonstration on the CO poisoning mechanisms and the alloy design principles for anodic HOR in PEMFCs, recent progress on CO-resistant Pt-based alloy catalysts for high-efficiency PEMFCs is briefly presented. Finally, future challenges and directions for the commercialization of Pt-based alloy catalysts are reviewed. This review offers the significant insights into Pt-based alloys as a cutting-edge strategy for enhanced CO tolerance and favorable HOR for high performance PEMFCs.

PEMFC阳极耐CO铂基合金研究进展及展望

全球变暖和能源消耗推动了质子交换膜燃料电池（pemfc）的研究和发展，质子交换膜燃料电池是一种高能量密度、零排放的能量转换装置。目前，用于pemfc阳极氢氧化反应（HOR）的主要商业催化剂是Pt/C，而CO在pemfc阳极反应物中的存在严重影响了Pt基催化剂的效率。过渡金属的加入可以修饰pt基催化剂的电子结构，降低CO在铂表面的吸附能，从而提高对CO的耐受性。本文旨在介绍pt基合金策略在PEMFC阳极抗co中毒和HOR性能优化中的关键作用，并提供当前研究领域的概述。通过对pemfc中CO中毒机理和阳极HOR合金设计原则的论证，简要介绍了用于高效pemfc的耐CO pt基合金催化剂的研究进展。最后，展望了pt基合金催化剂商业化的未来挑战和发展方向。这篇综述为pt基合金作为增强CO耐受性和高性能pemfc有利HOR的前沿策略提供了重要见解。
